Clay Bar Decontamination: What It Is and Why Your Paint Needs It
What clay bar and chemical decontamination remove from car paint, how to tell if your paint needs it and how it fits into an exterior detail.
Run your hand over freshly washed paint. If it feels rough or gritty, there are contaminants bonded to the surface that washing alone cannot remove. That is where decontamination comes in.
What builds up on paint
- Iron particles from brake dust and rail dust that embed in the clear coat.
- Industrial fallout and road tar.
- Tree sap and overspray.
- Salt and mineral residue near the coast.
Two kinds of decontamination
- Chemical decontamination dissolves iron particles and fallout. It is included in our Exterior Detail (from $175) and Executive Full Detail.
- Mechanical decontamination (clay) gently lifts bonded contaminants off the surface, leaving it smooth as glass. Clay / Mechanical Decon is available as an add-on from $75 to $125 by vehicle size.
Why it matters
- Sealants and coatings bond properly to clean paint.
- Paint looks clearer and glossier.
- Polishing is safer because grit is not dragged across the surface.
That is why decontamination is a standard step before every ceramic coating and paint correction we do.
Book an Exterior Detail and add clay decontamination if your paint feels rough.
